For something that can become a popular means of payment, you need the following:
Store of value: allowing individuals to make intemporal choices on when to spend their purchasing power
Medium of exchange: facilitating the exchange of goods and services by eliminating the inefficiencies associated with a barter economy
Unit of account: acting as a measure of value in the economic system.
Do you think the bitcoin has all three of these elements? I am looking forward to the bitcoin will become a popular payment method in the future.
I think bitcoin can fullfill that three element. Bitcoin can use as store of value and at same time, bitcoin is secure payment cryptocurrency. Bitcoin is secure cryptocurrency and no one can duplicate the transaction. Maybe thats why bitcoin become popular cryptocurrency in market
